Searched a little and apparently these are actual lithium batteries used in the newest disposable vapes. I guess they used the capacitor style because its a perfect fit inside a vape and so they can keep some tooling.

Anyways would it be safe to use as it has no protection circuit? The device i would use it with has all the management and stuff and, for now at least, im not planning on making a scuffed battery out of a bunch of these in parallel. Its mostly for shits and giggles.
